    • DETAILED DESCRIPTION
  • With reference to FIGS. 1 and 2, a lighting system 10 includes one or more LEDs 12 which are positioned on a mounting platform 14, defining a light engine 16. Wire leads 18, 20 are provided for powering the LEDs 12. The LEDs 12 is one of inorganic and organic light emitting devices which emit light in a spectrum from UV to infrared. Variations in optical performance, viewing angles, and intensity levels are achieved by arranging the LEDs in different patterns. The lighting system 10 includes a light cover or enclosure 22. Preferably, the enclosure 22 is a traditional bulb-shaped enclosure. Optionally, the enclosure 22 is a custom built enclosure to provide non-uniform light output to create special visual effects. It is contemplated that the enclosure 22 can be spherical, elliptical, cylindrical, domed, squared, n-sided, or any other shape. Preferably, the enclosure 22 is built of light transparent or translucent materials, or a combination thereof. The enclosure 22 materials are selected from glass, plastic, acrylic, polycarbonate, or other suitable materials.
  • Preferably, the platform 14 is a substrate on which a semiconductor may be grown. The platform 14 can be one of sapphire, gallium arsenide, silicon carbide, gallium phosphorous, gallium arsenide, gallium nitride, or other suitable material. It is also contemplated that the platform 14 can be a printed circuit board, heatsink, or any other suitable means for mounting the LEDs 12. The LEDs 12 are attached to the platform 14 by one of solder, wirebonding, thermosonic, thermocompression, electrical conductive adhesives, thermal conductive adhesives, other suitable means, or a combination of the above. It is also contemplated that the LEDs 12 can be adjacent to or manufactured as an integral part of the cover 22.
  • The platform 14 is adapted to be directly mounted into a base or socket 24. In one embodiment, the base 24 has a receptacle into which the light engine 16 is plugged in. Preferably, the base 24 is one of the commercially available light bulb sockets for easy field exchange and retrofitting of the light bulb with the LED light engine 16 such that the enclosure 22 can be fitted over the light engine 16. E.g., in one embodiment, the base 24 is one of commercially available incandescent light sockets such as 6S6 screw base, 194 wedge base, or other. Such design allows the conventional lamp to be replaced with a variety of different LED light engines without modification to the lamp socket or to the lamp enclosure. Optionally, the base 24 is custom manufactured. At least one heatsink 26 is integrally disposed in thermal communication with the light engine 16 and the base 24 to take the heat away from the LEDs 12. The heatsink 26 is constructed from the material capable of conducting the heat away from the LEDs 12. Examples of suitable materials include copper, aluminum, silicon carbide, boron nitride and others known to have a high coefficient of thermal conductivity.
  • Preferably, an index matching material 28 is applied to encompass the light engine 16 to improve the light extraction. The index matching material is selected from silicones, acrylics, epoxies, thermoplastics, glasses and any other appropriate materials. Optionally, an index matching fluid, which preferably serves as a thermal spreading medium, is present between the light engine 16 and the cover 22. The fluid is selected from solids, gels, liquids, fluorocarbon coolants, luminescent materials and others to create a desired visual effect. Additionally, reflective or translucent particles may added to the fluid for further visual effects. The cover 22 works together with the internal fluid to optimize light extraction and/or provide visual effects. In one embodiment, the index matching material 28 is structured to provide lensing.
  • In order to provide suitable electrical power to the LEDs 12, the lighting system 10 includes one or more of an electric power conversion circuit, or control electronics, or power electronics circuits 30, which are preferably integrated with the light engine 16. Alternatively, the electric power conversion circuit 30 can be adjacent the light engine 16, located within the base 24, or disposed remotely from the lighting system 10. In one embodiment, the electric power conversion circuit includes an AC/DC converter which permits the LED-based lighting system 10 to be powered by a standard domestic 120VAC or international 220VAC user voltage. Such circuitry makes the LED lamp a true replacement for a bulb light. Preferably, the power electronics circuits 30 are two- or three-dimensional structures to provide minimal dimensions. In one embodiment, the electric power conversion circuits 30 are flexible circuits. Optionally, the electric power conversion circuits 30 are non-planar circuit boards.
  • With reference to FIG. 3, the lighting system 10 includes a heat dissipating slug 32. The heat dissipating slug 32 is disposed in a thermal communication with the base 24 to conduct the heat from the light engine 16 into the base 24. Optionally, the heat dissipating slug 32 transfers the heat from the light engine 16 into the air. Preferably, the heat dissipating slug 32 includes a plurality of radial fins 34 disposed about an outer periphery of the slug 32.
  • With reference to FIG. 4, the heat dissipating slug 32 extends beyond the base 24 to transfer the heat from the light engine 16 into the air.
  • Optionally, the base 24 includes at least one of thermoelectric cooling, piezo synthetic jets, qu-pipes, heat-pipes, piezo fans and electric fans, or other forms of active cooling.
  • With reference to FIGS. 5 and 6, the lighting system 10 includes a wavelength converting material such as organic or inorganic phosphor. The phosphor can be located in any suitable location, such as integrated into the LED 12, at a light guide 36, coated inside or outside the cover 22, contained within the cover 22, or a combination thereof.
  • In one embodiment, the enclosure 22 includes transparent organic phosphors which are preferably coated on an inside, or outside surface of the enclosure 22, or a combination thereof It is also contemplated that the phosphors can be dissolved, melted, coextruded, or dispersed by any other means within the walls forming the enclosure 22. Preferably, the phosphor distribution is uniform. In one embodiment, the phosphor distribution is non uniform to create preselected patterns, figures, special visual effects of different colors, and other effects. It is also contemplated that both transparent and conventional non-transparent phosphors can be used to create special effects, patterns, or figures. In one embodiment, the enclosure 22 is frosted or otherwise treated to provide special visual effects. Examples of the organic transparent phosphors are the BASF Lumogen F dyes such as Lumogen F Yellow 083, Lumogen F Orange 240, Lumogen F Red 300, and Lumogen F Violet 570. Of course, it is also contemplated that other phosphors such as the rare earth complexes with organic component described in the U.S. Pat. No. 6,366,033; quantum dot phosphors described in the U.S. Pat. No. 6,207,229; nanophosphors described in the U.S. Pat. No. 6,048,616, or other suitable phosphors can be used.
  • With continuing reference to FIG. 5, the UV light rays 40 are emitted by the LEDs 12 and converted into white or visible light 42 by a phosphor 44. The phosphor 44 preferably includes two or more phosphors to convert the emitted light 40 to the visible light 42, although single component phosphors are embodied for saturated color light generation as well. The visible light 42 exits through the enclosure 22. In this embodiment, the phosphor mix 44 is disposed about or within a light guide 36 which is a planar panel disposed above the LED 12 such that the majority of the light rays 40 strike the panel.
  • With reference again to FIG. 6, the light guide 36 is a filament which is disposed within the enclosure 22 to create a “filament-look” LED based lighting system. More specifically, phosphor 44 is applied directly to the LED 12 such that the emitted light 40 is converted into visible light 42 at the LED 12. The visible light 42 strikes the light guide 36 and adapts the filament shape to simulate a “filament-look” light bulb. Alternatively, a suspended reflector may be used to simulate the filament shape. The reflector can be “wadded” tin foil, a coiled aluminized spring, or the like. Optionally, the light guide 36 is a coiled fiber optic with surface, internal, or other diffusers, such as frustrated TIR (Total Internal Reflection) diff-users, to allow the light to escape at the desired locations.
  • The invention has been described with reference to the preferred embodiments. Modifications and alterations will occur to others upon a reading and understanding of the preceding detailed description. It is intended that the invention be construed as including all such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
